A laboratory (informally, lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed.
Laboratories used for scientific research take many forms because of the differing requirements of specialists in the various fields of science and engineering.

Laboratory Control Sample (LCS) is a specimen of known composition prepared using contaminant-free reagent water, or an inert solid, that is spiked with the analyte of interest at the midpoint of the calibration curve or at the level of concern; and then analyzed using the same preparation, reagents, and analytical methods employed for regular specimens and at the intervals set in the QA Project Plan.

The Laboratory Data Qualifier is a Code applied to the data by the analytical testing facility to indicate a verifiable or potential data deficiency or bias.

Laboratory Duplicates are two or more representative portions taken from one homogeneous sample by the analyst and analyzed in the same testing facility.

Lactate means to secrete or produce milk.

Deutsch: Laktation / Français: Lactation / Italiano: Lattazione
